Opendrop
Opendrop is a Python implementation of the AirDrop protocol used for transferring files and links between devices over wireless connections. It functions as a peer-to-peer wireless file transfer system and a tool for automating the exchange of network passwords using specialized handshake mechanisms.
The project enables the discovery of nearby hardware by scanning for Bluetooth Low Energy advertisement packets and searching local subnets for specific service signatures. It establishes direct communication links through monitor mode and raw frame injection to move data without requiring a standard wireless access point.
The system covers a broad range of wireless capabilities, including device discovery, peer-to-peer networking, and the ability to send and receive files or web addresses by mimicking target hardware sharing logic.

Star history
How this analysis was created: This summary and feature list were written by an AI model that read the project's README and public documentation pages. Each feature links to the documentation it came from; stars, license and language come straight from the GitHub API. The model does not read the source code, and the analysis is refreshed when the project is re-analysed. Learn more on our About page.
